CREAM SEPARATOR.

Application filed April 8, 1924. Serial No. 704,983.

To all whom it may concern: 7

Be it known that I, Ror S. INNES, a citizen of the United States, residing at Madison, in the county of Lake and State of South 5 Dakota, have invented certain new and useful Improvements in Cream Separators, of

A further object of the invention is to provide a cream separator which dispenses with the necessity of the operators hands engaging the flexible disk that effects con1 pression of the air to initiate the siphoning action, thereby rendering the device more sanitary.

A still further object of the invention is t to provide an air-compression disk which has but a single'opening so as to not weaken same. i

The invention has still further and other objects which will be later set forth and of themselves manifested in the course of the following description.

In the drawings:

Figure 1, is a perspective View of the glass tubes;

Figure 2, is a side elevation showing the invention in use;

Figure 3, is a top plan view of the flexible disk, and

Figure 4, is a side edge elevation of Figure 3.

In proceeding in accordance. with the present invention, a substantially J-shaped siphoning tube 1 is employed to which is fused a short and preferably straight air tube 2. The tube 2 has its lower end portion of less diameter than its upper end portion forming an inclined shoulder 8, the latter located opposite to the curved inner face portion 1 of the loop of the tube 1, the parts 3 walls or parts. The upper end portion of the air tube 2 extends above the loop of the siphon tube 1 and is dispose-d in such relation thereto, so that the operator may grasp the e at a? 911 was; the 10 n one head the ingress of air thereinto.

and a forming divergently related a and with the thumb or one of the fingers engaged with and over the upper end of the air tube 2, so as to seal. the latter preventing It will thus be seen that the loop of the tube 1 and the upper end of the air tube 2 cooperate in forming a convenient hand grip for thetube for a purpose now to be set forth.

A preferably rubber or other flexible disk 6 is provided and which is thickened at its center, as indicated at 7, the upper face of the disk tapering from the thickened center toward the periphery of the disk. The

thickened center affords a reinforced portion in which a slngle and substantially elliptical opening 8 is formed, the latter of a slze to receive and tightly or frictionally engage the fused or connected parts of the tubes 1 and 2. The upper face of the thicl ened center of the disk is engaged by the divergently related parts8 and 4 of the tubes, the latter being wedged. into engagement with the walls defining the ends of the opening 8.

In operation, the disk 6 is placed on the top ofthe neck of a milk bottle B and a glass or other receptacle G placed beneath the long leg of the siphon tube. The operator then grasps the curved or looped'part of the siphon tube with his fingers and places his thumb or a finger on top of the upper end of the air tube 2, and presses downwardly on the tubes, causing depression of the central part of the disk with resultant compression of the air between the disk and the surface of the fiuid in the bottle. The short leg of the siphon tube is of a length to reach to about the bottom of the cream line, and upon compression of the air as just set forth the cream will be forced upwardly through the short leg of the siphon tube, over the curve or loop thereof and thence down the long leg into the receptacle. If the cream line or level varies, the tubes can be adjusted to cause the lower end of the short leg of the siphon tube to lie at the cream line and should the siphonage action be interrupted for any reason it can be restarted by the operator blowing air in the air tube.

What is claimed is: l

1. In a cream separator, a substantially J-shaped siphon tube, a substantially straight air tube having a reduced lower end fused to the short leg of the Siphon tube and forming an inclined shoulder located opposite to the curved part of the siphon tube and divergently related to the adjacent inner wall of said curved part, and a flexible disk formed to seat on top of a milk bottle and having a thickened center formed with a central elliptical opening to tightly and reinovably receive the fused parts of the tubes and to engage with each of said divergently related parts thereof the upper end of the air tube extending above the curved part of the siphon tube and related thereto whereby the operator may grasp the curved part in the fingers of one hand and with one of the fingers engaged over the upper end of the air tube to seal the latter and by pressing downwardly on said tubes effect depression of the center of the disk.

2. In a. cream separator, a substantially J-shaped siphon tube, an air tube rigidly connected to the short leg of the siphon tube and having a shoulder, a flexible disk formed to seat on top of a milk bottle and having a central opening reinovably reeeiw ing the tubes, said shoulder of the air tube being located opposite and adjacent to the curved part of the siphon tube whereby said shoulder and the said adjacent curved part form abutinents to each engage the upper face of the disk.

in testimony whereof I aflix my signature.

ROY S. INNES.
